STUFFING-BOX WITH REVERSIBLE GLAND.

Specification of Letters Patent.

Application filed November 5, 1906.

Patented March 10, 1908.

Serial No. 342,010.

' To all whom it may concern:

Be it known that I, GEORGE S. POWER, a citizen of the United States, anda resident of Passaic, in the county of Passaic and State of New Jersey,have invented certain new and useful Improvements in Stufling- Boxeswith Reversible Glands, ofwhich the following is a specification.

This invention relates to a stufling box, with a reversible gland. Itsobject is the production of a stuffing box with a gland, which latterwhen placed in one position can be used in the usual way with packingmaterial inserted between one of its edges and the edge of the neck ofthe box, and when its position is reversed a packing ring on the glandperforms the functions of the packing material.

The stufling box and gland is especially ap licable to a piston workingwith air when a anged packing ring is used therewith, and for steam whenthe usual packing material is employed.

In the accompanying drawings which exemplify the invention, Figure 1represents an elevation of the neck of a rock drill cylinder,

containing a stuffing box with the improved gland, Fig. 2 shows a topplan view of Fig. 1, Fig. 3 is a section of Fig. 2, on the line 3, 3,Fig. 4 is a partial elevation and section of Fig. 2 on the line 4, 4,with the gland placed in an inversed position, Fig. 5 is a top plan viewof the gland, Fig. 6 is a artial elevation and section of Fig. 5 on theinc 5, 5. Figs. 7 and 8 show vertical sections on a reduced scale ofmodifications of the invention.

A neck 10 of a rock drill is shown with the beveled edge 11, upon whichbears the reversible gland 12, having the flanged packing ring 13, thelatter bein preferably made of leather or the like pliab e material. Thepacking ring is supported in a groove 14 formed in the gland, whichlatter is preferably split as shown on the line 15, 15, and its edge 16is generally beveled. The gland is counterbored at 17 below the groove14, and its outer surface bevels both ways from about itscentralportion, as represented at 18 and 19. I

The neck 10 is threaded at 20 for a cap 21, and the latter has a beveledopening 24 through its upper end, that engages with either one of thebeveled surfaces of the gland.

In Fig. 4 the gland is placed in a reversedposition, the flanged packingring being travel in the direction of the arrow in said figure, thepressure will tend to force the cylindrical body of the packing ringagainst.

the piston rod 23 and prevent leakage.

When the gland is used with a steam cylinder the parts are located asshown in Fig. 4, with a packing material 22 inserted between the loweredge of the gland and the top edge of the neck of the stuffing box.

It will be noted that by reversing the position of the gland it is madeapplicable for use, either with an air or steam operated piston.

In Fig. 7 there is represented the neck 30 of a stufling box with itspiston rod 31, on the upper face 32 of which is placed a gland 33 withthe flanged packing ring 34, which latter extends from a counterbore inthe upper face of the gland. The gland tapers on its sides 35 from itsupper to its lower face. A collar 36 with sides 37 flaring out from itsupper to its lower face is placed on top of the gland. A cap 38 withflaring walls 39 on its upper inner sides is screwed on the neck andengages the sides 37 of the collar 36.

In Fi 8 is shown a neck 40 of a stufling box wit the piston rod 41. Onthe upper edge 42 of the neck is placed a gland 43 similar to the gland33 with the flanged packing ring 44. A cap 45 in engagement with theneck 40 bears on the gland 43.

In Figs. 7 and 8 both glands are shown located for use with an airpiston, and it is evident that if in Fig. 7 the locations of the gland33 and collar 36 arereversed, and a packing material placed on top ofthe upper face 32 of the neck 31 and theflanged packing removed, thatthe stuffing box with its gland will be applicable for use with steam.

In Fig. 8 if the position of the gland 43 is reversed under the cap 45,and packing material inserted between the gland and to face 42 of theneck 40 the stufling box wiil also be applicable for steam. In theglands represented in Figs. 7 and 8 there is no necessity of splittingthem as for the gland 12, although it may be done.

Having described my invention, I claim:

1. The combination with a stuffing box of a neck, a cap in engagementwith the upper end of the neck, a gland having a groove 5 thereinlocated in the cap axially in line with l the neck, and a flangedpacking ring extending from the groove of the gland.

2. 'I he combination with a stufing box of a neck therefor, a cap inengagement with the upper end of the neck, a split gland having a groovethereon located axially in line with the neck and bearing upon the upperedge thereof, a piston rod passing through the stuffing box, a flangedpacking ring extending from the groove and bearing on the piston rod.

3. 'I he combination with a stuffing box of a neck therefor, a cap inengagement with the upper end of the neck, a split reversible glandlocated axially in line with the neck and bearing upon the upper edgethereof, a piston rod passing through the stuffing box, and packingmaterial inserted between the lower edge of the gland and the upper edgeof the neck of the stuffing box.

4. The combination with a stufling box of a neck therefor, a cap havinga beveled opening in enga ement with the upper end of the neck, a splitreversible gland located axially in line with the neck and bearingthereon and having a beveled surface in engagement with the beveledopening in the cap, a piston rod passing through the gland and stuflingbox, and a flanged packing ring extending from the gland bearing on thesaid. rod.

5. The combination with the neck of a stufling box, of a reversiblegland axially in line with the neck and bearing on the upper edgethereof, a piston rod passing through the stuffing box, a packing ringextending from the gland, a collar on the gland, and a cap engaging withthe neck and inclosing the gland and collar.

6. The combination with the neck of a stuffing box, a cap in engagementwith the upper end of the neck, a split gland located axially in linewith the neck and bearing upon the upper edge thereof, a piston rod.passing through the stulling box, and a p ack ing ring extending fromthe gland.
